The U80701 was a 32-bit microprocessor developed from 1986-1990 in the German Democratic Republic. It was manufactured by VEB Mikroelektronik "Karl Marx" Erfurt (MME) in NMOS technology and encased in a CQFP-68 package.
The U80701 was developed by reverse engineering the MicroVAX 78032 microprocessor of the Digital Equipment Corporation (DEC). It was used in the Robotron K 1820 minicomputer - a clone of DEC's MicroVAX II.
The U80700 system includes the following chips:
- U80701: CPU (DC333)
- U80703: FPU (DC337)
- U80707: Console interface/controller DLART (DC319)
- U80709: CPU interface gate array (DC379)
- U80711: Q22-Bus interface gate array (DC380)
